✦ Synopsis
In the presence of cesium carbonate, a variety of aldehydes can be epoxidized directly with ally1 bromide at 50°C under solid-liquid phase transfer condition by use of a catalytic amount of diisobutyl telluride to afford vinyl epoxides in good yields with predominant cis stereoselectivity.
